AGN STORM 2. XI. Spectroscopic reverberation mapping of the hot dust in Mrk 817

Hermine Landt, Benjamin D. Boizelle, Michael S. Brotherton +41

The AGN Space Telescope and Optical Reverberation Mapping 2 (STORM 2) campaign targeted Mrk 817 with intensive multi-wavelength monitoring and found its soft X-ray emission to be s…

The first spectroscopic IR reverberation programme on Mrk 509

J. A. J. Mitchell, M. J. Ward, D. Kynoch +12

Near IR spectroscopic reverberation of Active Galactic Nuclei (AGN) potentially allows the infrared (IR) broad line region (BLR) to be reverberated alongside the disc and dust cont…

A complex dust morphology in the high-luminosity AGN Mrk 876

Hermine Landt, Jake A. J. Mitchell, Martin J. Ward +9

Recent models for the inner structure of active galactic nuclei (AGN) advocate the presence of a radiatively accelerated, dusty outflow launched from the outer regions of the accre…

The SOUX AGN Sample: SDSS-XMM-Newton Optical, Ultraviolet and X-ray selected active galactic nuclei spanning a wide range of parameter space -- Sample definition

Daniel Kynoch, Jake A. J. Mitchell, Martin J. Ward +3

We assemble a sample of 696 type 1 AGN up to a redshift of , all of which have an SDSS spectrum containing at least one broad emission line (H , H or Mg II) and an XM…

The SOUX AGN sample: Optical/UV/X-ray SEDs and the nature of the disc

Jake A. J. Mitchell, Chris Done, Martin J. Ward +4

We use the SOUX sample of 700 AGN to form average optical-UV-X-rays SEDs on a 2D grid of and . We compare these with the predictions of a new AGN…

Detection of an Unidentified Soft X-ray Emission Feature in NGC 5548

Liyi Gu, Junjie Mao, Jelle S. Kaastra +17

NGC~5548 is an X-ray bright Seyfert 1 active galaxy. It exhibits a variety of spectroscopic features in the soft X-ray band, including in particular the absorption by the AGN outfl…

AGN STORM 2: I. First results: A Change in the Weather of Mrk 817

Erin Kara, Missagh Mehdipour, Gerard A. Kriss +69

We present the first results from the ongoing, intensive, multi-wavelength monitoring program of the luminous Seyfert 1 galaxy Mrk 817. While this AGN was, in part, selected for it…
